DURANOL™ is a polycarbonate diol that contributes to the high performance of polyurethane resins not only in hydrolysis resistance, but also in tactility, flexibility, chemical resistance, and abrasion resistance.
Feature
- Achieve both flexibility and durability
- Reduction of VOCs
- Bio-polyurethane
Usage
- Synthetic leather for car seats
- Interior and exterior paints
- Soft-feel paint for interior paints
DURANOL™ improves the durability of synthetic leather and adds functionality. In the automotive painting process, it contributes to VOCs reduction.

Achieve both flexibility and durability
DURANOL™ is available in a wide range of liquid grades, enabling both flexibility and durability in polyurethane resin products. In addition to resistance to hydrolysis, DURANOL™ offers abrasion resistance, chemical resistance such as sunscreen and DEET, and stain resistance against color migration on jeans. Therefore, it can maintain the aesthetic appearance of interior parts and car seats for a long period of time.
Reduction of VOCs
Our liquid grades contribute to reduced solvent usage and higher solids content in paints due to their high solubility. The water-dispersion series contributes to reduced VOCs by making paints water-based and reduces handling risks at workplaces, thereby improving safety.
Bio-polyurethane
DURANOL™ has a lineup of bio-based grades. Since BPN02 is made from bio-based raw materials and has a high carbonate content, it contributes to both high performance and bio-oriented polyurethane resin products.
Synthetic leather for car seats
Duranol™ enhances important properties such as chemical resistance, abrasion resistance, hydrolysis resistance, and flexibility in the “Leather Finish Layer,” “Skin Layer,” “Adhesive Layer,” and “Wet Layer” that make up synthetic leather. For example, it improves abrasion resistance in the leather finish layer, enhances chemical resistance in the skin layer, optimizes hydrolysis resistance in the adhesive layer, and improves flexibility in the wet layer.
*Leatherfinish layers using ether-based polyols or conventional solid grades show significant damage from sunscreen creams. On the other hand, surface treated layers with Duranol™ BPN02 show virtually no damage from sunscreen creams.
Interior and exterior paints
Due to its high solubility, DURANOL™ contributes to the reduction of solvent usage through the high solid content in the paint. In addition, AKN11 and other water-dispersion series have attracted particular attention because of their ability to be dispersed in water. DURANOL™ also contributes to the high performance of polyurethane dispersions (PUD) and can be used in waterborne coatings.
Soft-feel paint for interior paints
Soft-feel paints using DURANOL™ convey a sense of luxury and uniqueness to users and bring about product differentiation.
DURANOL™ is a polycarbonate diol (PCD) and is mainly available as a liquid grade at room temperature, and has been used in many end products as a soft-feel paint, mainly in our T5652 product.
